Is there a iOS 6.1.3 jailbreak for iPhone 4S?

I feel like they have it somewhere. I ran into this video with people saying it worked: http://www.youtube.com/...C8RjNU81L4

So this tells me it is possible to jailbreak iphone 4s on 6.1.3

Yea you can give it a try, online sources states that it works. I would just try it if I were you, if halfway you suspect something's wrong then just stop what you are doing.

Yea its available but the process is little bit difficult

There's NO Jailbreak available for 6.1.3 all websites offering such stupid adds are fake, if you r too rich to spoil your device you can move ahead and try them out, otherwise wait for 2 months and ios7 jailbreak would be available.
